SPRINKLER HEAD.

Application file d December a1, 1926. Serial No. 158138. I

This invention relates to sprinkler. heads,

and more particularly to-sprinkler heads such as are commonly used in watering lawns and gardens, and which areprovided with a part adapted to be rotated by the force'of the water as it is discharged, and which rotatin'gspart is effective to breakup astream of water intoa Suitable s ray. y 1 The ob ects of the invention are to provide a sprinkler of the class described which will be effective to prod'uceanevenly distributed spray of water; to provide means for facilitating rotation of the rotating part, and in general, to provide a sprinkler head of the class described which Will not readily Wear away, due to the rotation of the rotating partand which will consequently, give lasting efficient service... 5 h v Further objects and advantages. will be understood by reference to the following "specification in connection with the zaccom- I panying drawing in which I have illustrated a selected" embodiment of my invention and in which I Fig. 1 is a side elevation, and Fig. 2 is a sectionon the. line 2 -2 of Fig. 1'. Fig. 3 is a section on the line of Fig. 1.

Referringnow to the drawings, I-have illustrated a nozzle 5 having an enlarged end portion' 6 provided with an internal screw threading 7, adapted to be connected to a stand pi e or to the end of a garden hoseor the like. T 1e nozzle 5 is centrally apertured as at 8 with-a gradually tapering aperture which'at the u per or discharge end 9 of theqnozzle is slightly smaller than atitslowerend. J i

The upper end of the :nozzle is provided" with a re uced bearing portion 10 which is adapted to receive the lower end 11 of a rotatable member 12. The'said lower'end 11 consists of a ring-like band which embraces the I bearing portion 10 of the nozzlewhereby the rotating member 12 is rotatably mounted at its lower end of the nozzle.

The upper end of the rotating member rotatably supported by means of an anti-friction bearing which preferably comprises a combination radial and. end thrust ball bearing. This bearing consists of outer and inner races:13 and 14respectively, which are I break up the stream of water into a suitable provided with oppositely disposed ball races disposed between the said ballraces and are 15 and 16'respectively. Suitableballs 17'are adapted to permit 'free rotation of the inner racelfiiu the outer race 13 is formed so asto provide an endwall18 and a sidewall 19 and the inner ball, race 16, is formed in the race :14 so asto provide an end wall 20 and a sidewall 21, which areres'pectively disposed opposite theend'and side walls of the outer race. It will be obvious that end-thrust between the inner and out er race members-is taken up by I the balls 17 between the end walls 18 and 20 andthat radial thrustbetween the said members is taken up between the walls 19 and 21. A casing 22 embraces a portion of the outer race 13 and extends over a portion 33of the inner race as at 24, so as to prevent separation of the two parts of the bearing.

The member 22 ispreferably a sheetmetal member which may readily be swaged over the said parts.

The bearing member is mounted in a cuplike holder 25 comprising an annular side wall 26 and a bottom 27 which is axially apertured as at 28 to permit, connection between the upper end 29 of the rotatable part 12 and the inner race 14 of the bearing member. Connection between these two members is preferably accomplished by means of a screw 30 exrace 14 of the bearing member and threadedly lengaging the upper end of the rotating part,-

suitable bosses 31 and 32 preferably being provided on the connected parts for facilitating tending .througha suitable aperture in the 1 of a pair of. arms 33 and 34 which are preferablyintegral with the nozzle an-d'which-exe. tend upwardly anddiverge outwardly there fromyand which are rebentasat 35 and 36 so as to connect with said cupesliaped member, these members also preferably being integral.

The rotating part12 includes a channel like portion indicated at 37, disposed above its lower end 11. and which is shaped so that Water discharged from the nozzle is caused to follow a wurse approximately such. as indicated by the arrow 38 and whereby pressure is exerted against one wall of'the channeled portion of the rotating part. such pressure being exerted off-center in the vicinity indicated by the arrow head 39. Such pressurecauses the part 12 to rotate rapidly on its bearings and the projecting portion or fin 40 is effective to 'member as above described. The bearing lit) member may be secured in the cup 25 in any suitable manner, which in the present embodiment consists merely of frictional engagement between the outside of the member 22 and inside of the cup 25. I may also swage the upper end of the cup 25 over the adjacent end of the bearing to provide a positive holding means.

I am aware that various changes in the form and construction of my improved sprinkler head may be made without departing from the spirit of the invention which should be determined by reference to the following claims. 1

I claim as my invention':'

1. In a sprinkler head of the classdescribed, the combination of a nozzle, a'spraying member adapted to be rotated by pressure of water discharged from said. nozzle, means for rotatably supporting said spraying member in operative position relative to said nozzle, said means comprising a bearing portion on the upper end of said nozzle, a bearing member on the lower end of said spraying member for engaging said nozzle bearing portion, combination racial and end thrust ball beat ing anti-friction means for the upper end of said spraying member, and means for mounting said ball bearing anti-friction means comprising a cup-shaped memberhaving an axial aperture in its bottom, means integral with said nozzle for supportingsaid cup-shaped member in fixed position relative to said nozzle, said cup-shaped member being adapted to receive said ball bearing anti-friction means and said spraying member being' connected to a part of said ball bearing antifriction means through said axial aperture.

2. In a sprinkler of the class dc, cribed, the combination of a nozzle, a spraying member rotatably mounted at one end on said nozzle and adapted to be rotated by the force of fluid discharged therefrom, such. force normally tending to force the spraying member away from the nozzle, and means for rotatably supporting the outer end of said spraying member and effective to retain the member in operative position relative to the nozzle, said means including an annular bearing member fixedly connected to said nozzle. a bearing portion adjacent the outer end of said spraying member and rotatably mounted in said annular bearing member, and a plurality of anti-friction members interposed between said bearing portion and annular bearing member for facilitating rotation of the spraying member.

' 3. In a sprinkler of the class described, the combination of a nozzle, a spraying member rotatably mounted atone end on said nozzle and adaptedfto. be rotated by the force of fluid discharged therefrom, such force normally tending to force the spraying memberaway from the nozzle, and: means for rotatabysupporting the outer end of said spraying member and effective to retain the member in operative positionrelative to the nozzle, said means including'an annular member fixedly connected to said nozzle, a ballbearing member mounted in said annular member and including'inner and outer races and a plurality of balls interposed between said races For-facilitating rotation oi? the innor race within said outer race, and said inner race being connected to the outer end of said spraying member so as to rotatably support said outer end.

i. In a sprinkler of the class clcecribed,;the combination of a nozzle, a spraying member rotatably mounted at one end on said nozzle and adapted to be rotated by the force of fluid discharged therefrom, such force normally tending to force the spraying member away from the nozzle, and means for rotatabl supporting the outer end of said spraying member and eflective to retain the member in operative position relative to the nozzle, said means including an annular member fixedly connected to said nozzle, a combination radial and end-thrust ball-bearing incur ber mounted in said annular member and including inner and outer races and a plurality of balls. interposed. between-said races for facilitating rotationof the inner race within said outer race, and said inner race being connected to the outer end of said spraying member so as to rotataliily support said outer end.
